Description

Technical Field

[0001] This utility model relates to the technical field of mold changing devices, specifically a magnetic template quick mold changing device. Background Technology

[0002] A mold changing device is a piece of equipment used for quickly changing molds or tools. It is widely used in various mechanical equipment in manufacturing, such as injection molding machines, die casting machines, and stamping machines. Its main purpose is to reduce downtime, improve production efficiency, and ensure accuracy and consistency after each mold change.

[0003] Based on the above, the inventors have discovered the following problems: Current magnetic templates typically use electromagnets to fix the templates, which require continuous power supply to maintain the magnetic field. Power outages may cause the templates to loosen or even fall off, increasing safety hazards and making them inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a magnetic template quick mold changing device in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic template quick mold changing device to solve the problems mentioned in the background art.

[0006] A magnetic template quick-change device includes a fixing component, a template component on the top of the fixing component, the template component including a module, a second permanent magnet block fixedly installed at the bottom of the module, and locking grooves at both ends of the module. The fixing component includes a housing, a lifting cavity is formed inside the housing, a partition is fixedly installed in the middle of the inner side of the lifting cavity, a lifting plate is slidably connected inside the lifting cavity, a first permanent magnet block is fixedly installed on the top of the lifting plate, wedges are fixedly installed at both ends of the lifting plate, limit grooves are formed inside both ends of the housing, locking blocks are slidably connected inside the limit grooves, one end of the locking block is set inside the locking groove, and a wedge groove is formed at the bottom of the locking block, with the wedge block slidably connected to the wedge groove.

[0007] By adopting the above technical solution, the setting of the second permanent magnet block facilitates the magnetic connection between the first and second permanent magnet blocks to fix the template assembly. The setting of the locking groove facilitates the insertion of the locking block into the locking groove, thereby fixing the template assembly inside the fixing assembly. The setting of the partition facilitates the isolation of the module from the lifting plate, allowing the lifting plate to descend and move the first permanent magnet block away from the second permanent magnet block, thus rapidly weakening the magnetic force. The setting of the first permanent magnet block facilitates the magnetic connection between the first and second permanent magnet blocks when the lifting plate rises and fits against the bottom of the partition, thereby fixing the template assembly. The sliding connection between the wedge block and the wedge groove facilitates the rise and fall of the lifting plate, which in turn drives the wedge block to rise and fall. When the wedge block rises, it inserts into the wedge groove, causing the locking block to extend and insert into the locking groove, thereby locking the template assembly inside the fixing assembly. In the event of a power outage, the attraction and fixation of the first permanent magnet block to the second permanent magnet block is not affected, and the locking block inserted into the locking groove further improves stability and prevents loosening and falling off.

[0008] Furthermore, telescopic rods are fixedly installed at both ends inside the lifting cavity, and the output end of the telescopic rods is fixedly connected to the lifting plate.

[0009] By adopting the above technical solution, the telescopic rod facilitates the control of the lifting plate's up and down movement, thereby controlling the locking and unlocking of the template assembly by the fixed components. Furthermore, the telescopic rod has a self-locking function, which is convenient for self-locking during power outages.

[0010] Furthermore, guide grooves are provided at both the top and bottom ends of the locking block, and the guide grooves are slidably connected to the limiting slide groove.

[0011] By adopting the above technical solution and setting the guide groove, it is convenient to guide and position the sliding of the lock block, thereby improving the stability of the lock block sliding.

[0012] Furthermore, spring seats are fixedly installed at both ends of the lock block, and a return spring is fixedly installed on one side of the spring seat.

[0013] By adopting the above technical solution and setting the reset spring, when the lifting plate moves downward and drives the wedge block to slide out of the wedge groove, it can provide elastic force to retract the locking block, so that the locking block slides out of the locking groove and unlocks the template assembly.

[0014] Furthermore, end plates are fixedly installed at both ends of the partition, and a lifting groove is provided at the bottom center of the end plate.

[0015] By adopting the above technical solution and setting the lifting groove, the end plate can be made to move the wedge up and down without obstructing its movement.

[0016] Furthermore, a through groove is provided at the top of the lifting groove, and the through groove is sleeved on the outside of the locking block.

[0017] By adopting the above technical solution, the through slot design allows the locking block to pass through the through slot and insert into the locking slot, thereby locking the template component.

[0018] Furthermore, spring grooves are provided at both ends of the through groove, and the spring grooves are fixedly connected to the other end of the reset spring.

[0019] By adopting the above technical solution, the spring groove facilitates the fixing of one end of the reset spring, enabling the reset spring to stably push the lock block to reset and unlock.

[0020] Furthermore, a mold groove is provided at the center of the top of the module, and lifting grooves are provided at both ends of the top of the module.

[0021] By adopting the above technical solution and setting up the hoisting slot, it is convenient for external equipment to hoist and replace the movable template components during mold changing.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: The inclusion of a second permanent magnet facilitates the magnetic connection between the first and second permanent magnets in the fixing assembly, thus securing the template assembly. The locking groove facilitates the insertion of a locking block, fixing the template assembly inside the fixing assembly. The partition plate isolates the module from the lifting plate, allowing the lifting plate to descend and move the first permanent magnet away from the second permanent magnet, thereby rapidly weakening the magnetic force. Furthermore, the inclusion of the first permanent magnet ensures that when the lifting plate rises and contacts the bottom of the partition plate, the first and second permanent magnets... The template assembly is fixed by magnetic attraction. A wedge block slides into a wedge groove, facilitating the rise and fall of the lifting plate. When the wedge block rises, it inserts into the wedge groove, causing a locking block to extend and insert into the locking groove, thus locking the template assembly inside the fixed assembly. Even during power outages, the attraction and fixation of the first permanent magnet block to the second permanent magnet block remains unaffected. Furthermore, the locking block's insertion into the locking groove further enhances stability, preventing loosening and detachment. This invention provides stable fixation of the template assembly during power outages, preventing loosening and detachment, and possesses high practical value. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5This utility model provides a technical solution: a magnetic template quick-change device, including a fixing component 1, a template component 2 on the top of the fixing component 1, the template component 2 including a module 21, and a second permanent magnet block 25 fixedly installed at the bottom of the module 21. The second permanent magnet block 25 facilitates the fixing component 1 to use a first permanent magnet block 106 to magnetically connect with the second permanent magnet block 25 to fix the template component 2. Locking slots 24 are provided at both ends of the module 21, facilitating the insertion of locking blocks 108 into the locking slots 24. The template component 2 is fixed inside the fixing component 1. The fixing component 1 includes a housing 101, and a lifting cavity 102 is formed inside the housing 101. A partition 110 is fixedly installed in the middle of the inner side of the lifting cavity 102. The partition 110 facilitates the isolation of the module 21 from the lifting plate 105, allowing the lifting plate 105 to descend and move the first permanent magnet block 106 away from the second permanent magnet block 25, thereby rapidly weakening the magnetic force. The lifting plate 105 is slidably connected inside the lifting cavity 102, and the first permanent magnet is fixedly installed on the top of the lifting plate 105. Block 106, through the setting of the first permanent magnet block 106, facilitates the magnetic connection between the first permanent magnet block 106 and the second permanent magnet block 25 when the lifting plate 105 rises and fits against the bottom of the partition 110, thereby fixing the template assembly 2. Wedge blocks 107 are fixedly installed at both ends of the lifting plate 105. Limiting grooves 104 are opened inside both ends of the outer shell 101. Locking blocks 108 are slidably connected inside the limiting grooves 104. One end of the locking block 108 is set inside the locking groove 24. A wedge groove 115 is opened at the bottom of the locking block 108. The wedge block 107 and the wedge The groove 115 is slidably connected, and the wedge block 107 is slidably connected to the wedge groove 115, which facilitates the rise and fall of the lifting plate 105 to drive the wedge block 107 to rise and fall. When the wedge block 107 rises, it is inserted into the wedge groove 115, which drives the locking block 108 to extend and be inserted into the locking groove 24, thereby locking the template assembly 2 inside the fixing assembly 1. When the power is off, it does not affect the attraction and fixation of the first permanent magnet block 106 to the second permanent magnet block 25. Moreover, the locking block 108 is inserted into the locking groove 24, which can further improve stability and prevent loosening and falling off.

[0031] The lifting cavity 102 has telescopic rods 103 fixedly installed at both ends. The output end of the telescopic rods 103 is fixedly connected to the lifting plate 105. The telescopic rods 103 facilitate the operation of the lifting plate 105 to move up and down, thereby controlling the locking and unlocking of the template assembly 2 by the fixing component 1. The telescopic rods 103 also have a self-locking function, which is convenient for self-locking during power outages.

[0032] The locking block 108 has guide grooves 114 at both the top and bottom ends. The guide grooves 114 are slidably connected to the limiting slide groove 104. The guide grooves 114 facilitate the guiding and positioning of the sliding of the locking block 108, thereby improving the stability of the sliding of the locking block 108.

[0033] Among them, spring seats 113 are fixedly installed at both ends of the locking block 108, and a reset spring 109 is fixedly installed on one side of the spring seat 113. By setting the reset spring 109, when the lifting plate 105 moves downward and drives the wedge block 107 to slide out of the wedge groove 115, it can provide elastic force to retract the locking block 108, so that the locking block 108 slides out of the locking groove 24, thereby unlocking the template assembly 2.

[0034] Among them, end plates 111 are fixedly installed at both ends of the partition 110. A lifting groove 117 is provided in the middle of the bottom end of the end plate 111. The lifting groove 117 facilitates the end plate 111 to move the wedge 107 up and down without obstructing it.

[0035] The top of the lifting groove 117 is provided with a through groove 116, which is sleeved on the outside of the locking block 108. The through groove 116 allows the locking block 108 to pass through the through groove 116 and be inserted into the locking groove 24 to lock the template assembly 2.

[0036] The through groove 116 has spring grooves 112 at both ends. The spring grooves 112 are fixedly connected to the other end of the reset spring 109. The spring grooves 112 facilitate the fixing of one end of the reset spring 109, so that the reset spring 109 can stably push the lock block 108 to reset and unlock.

[0037] The module 21 has a mold groove 22 at the top center and lifting grooves 23 at both ends of the top. The lifting grooves 23 facilitate the external equipment to lift and move the template assembly 2 for replacement when changing the mold.

[0038] Specifically, the working principle of this magnetic template quick-change device is as follows: During use, the lifting slot 23 facilitates the lifting and moving of the template assembly 2 by external equipment during template changes. The second permanent magnet block 25 facilitates the magnetic connection between the first permanent magnet block 106 and the second permanent magnet block 25 to fix the template assembly 2. The locking slot 24 facilitates the insertion of the locking block 108 into the locking slot 24, thus fixing the template assembly 2 inside the fixing assembly 1. The partition plate 110 facilitates the isolation of the module 21 from the lifting plate 105, allowing the lifting plate 105 to descend and allow the first permanent magnet block 25 to be used. The magnetic block 106 can move away from the second permanent magnet block 25, thereby rapidly weakening the magnetic force. The telescopic rod 103 facilitates the control of the lifting plate 105's up-and-down movement, thus controlling the locking and unlocking of the template assembly 2 by the fixing component 1. The telescopic rod 103 also has a self-locking function, facilitating self-locking during power outages. The guide groove 114 guides and positions the sliding of the locking block 108, improving its stability. The return spring 109 provides elastic recovery when the lifting plate 105 moves downwards, causing the wedge block 107 to slide out of the wedge groove 115. Block 108 allows the locking block 108 to slide out of the locking groove 24, thereby unlocking the template assembly 2. The lifting groove 117 ensures that the end plate 111 does not obstruct the up and down movement of the wedge block 107. The through groove 116 allows the locking block 108 to pass through the through groove 116 and insert into the locking groove 24, thereby locking the template assembly 2. The spring groove 112 allows one end of the return spring 109 to be fixed, enabling the return spring 109 to stably push the locking block 108 to reset and unlock. The first permanent magnet block 106 facilitates the lifting plate 105 to rise and fit against the bottom of the partition 110. The first permanent magnet 106 and the second permanent magnet 25 are magnetically connected to fix the template assembly 2. The wedge 107 is slidably connected to the wedge groove 115, so that the rise and fall of the lifting plate 105 can drive the wedge 107 to rise and fall. When the wedge 107 rises, it is inserted into the wedge groove 115, which drives the locking block 108 to extend and be inserted into the locking groove 24, thereby locking the template assembly 2 inside the fixing assembly 1. When the power is off, the attraction and fixation of the first permanent magnet 106 to the second permanent magnet 25 is not affected. Moreover, the locking block 108 is inserted into the locking groove 24, which can further improve the stability and prevent loosening and falling off.
